Diff Noise
Since I bought my car it has made a whining from the rear end and just about any speed. You can hear it from outside the car, down the street according to my friend. The sound goes away under throttle I think. I notice some bucking or a kind of "slack" in the drivetrain below 2000 rpm...Im not positive its the drivetrain and not the car running rich and bucking under decel with the haltech. I think its the preload adjustment on the diff. Anyone have any ideas? I pulled the plugs to replace the oil and it looks fine. Oh yeah and its a 4.33 installed by mazda

My FC used to have a whine but only when the clutch was in but I was in gear like taking a turn and shiftin to 2nd but still have the clutch in, a few months later my tranny crapped out and when i swapped trannys I noticed there was absolutely no gear lube in it...
Apparently the previous owner didnt bother to ever check the level of tranny lube... I do that once in a while now...
